The correct statements from the following are :

(A) The decreasing order of atomic radii of group 13 elements is $\mathrm{Tl}>\mathrm{In}>\mathrm{Ga}>\mathrm{Al}>\mathrm{B}$.

(B) Down the group 13 electronegativity decreases from top to bottom.

(C) $\mathrm{Al}$ dissolves in dil. $\mathrm{HCl}$ and liberates $\mathrm{H}_2$ but conc. $\mathrm{HNO}_3$ renders $\mathrm{Al}$ passive by forming a protective oxide layer on the surface.

(D) All elements of group 13 exhibits highly stable +1 oxidation state.

(E) Hybridisation of $\mathrm{Al}$ in $[\mathrm{Al}(\mathrm{H}_2 \mathrm{O})_6]^{3+}$ ion is $\mathrm{sp}^3 \mathrm{d}^2$.
